* Plots look nicer, render up to 4 times faster, and are more correct at 
very small and very large scales. New features include customizable dual 
axis ticks and transforms (e.g. log axes, date and currency ticks, axis 
interval collapse and stretch), stacked histograms, and 3D vector 
fields. The legacy `fit' function and libfit have been removed.
